Google Tag Manager seems like such a great tool the first time you ever use it, especially for non-technical users.

But the moment you add any level of complexity, you feel like Hansel and Gretel waking up from a sugar high and realizing they are trapped in a witch’s house. Here are things we consistently hear from data engineers about GTM:

Code injection is a mess and vulnerable to security issues

It’s heavily blocked and slows site performance

It’s difficult to manage user states at scale

Thankfully, there’s a better way. (Hint, it’s not using GTM at all!)

Dig into a detailed explanation of the problems GTM creates for data engineers, as well as how you can use RudderStack to much more efficient, scalable and secure data layer functionality.
